BOILER AND FURNACE ASH lP AN.

Specification of Letters Patent. Patented Sept. 3, 1918.

Application filed December 7, 1917. Serial No. 205,937;

To allwhomz't may concern." 7

Be it known that I, JOHN J. PRooHAzKA, a citizen of the United StatesofAmerica, and a resident of Chicago, in the county of Cook, State ofIllinois, have invented certain new and useful Improvements in Boilerand Furnace Ash-Pans, of which the following is a specification.

This invention relates to that class of ash pans used in connection withthe ash pits of house heating furnaces and boilers and has for itsobject To provide a structural formation and association of parts,whereby all the ashes that drop from the grate are directed into a panor receiver of convenient size, thereby avoiding dust and the use of ashovel .in removing the ashes, and whereby a removal ofthe appliance canbe conveniently accomplished where through neglect of the. attend ant,the ash pit of the furnace becomes unduly filled with ashes, all as willhereinafter more fully appear.

In the accompanying drawings Figure 1, is a perspective View of an ashpan having the present improvement ap plied.

Fig. 2, is a detail perspective view of one of the deflector plates in adetached condition.

Fig. 3, is a similar view of one of the pivot rods.

. Fig. 4, is a horizontal sectional view showing the present ash panstructure in place in a furnace ash pit. 1

Fig. 5, is a transversesection of the same on line 55, Fig. 4, likereference numerals indicate like parts in the several views.

Referring to the drawing, 1 designates the vertical inclosingwall as afurnace ash pit of a round or other usual form, andhaving an entranceopening or doorway 2, as shown.

3 designates an ash pan of the usual open top, and preferably formedwith straight and parallel side walls as shown, The present improvementinvolves in connection with the above described or usual construction ofa furnace ash pit and removable ash pan, a detail structure as follows 4designates a pair of deflector plates movably associated with opposedside walls of the ash pan '3 by detachable hinge connections as follows:

6 and 7 designate interengaging pivot knuckles or eyes, formed on oneedge of each deflector plate 4 and on an edge of each side wall of theash pan 3, and adapted to receive a pivot rod 8 by which the parts areconnected together in a pivotal manner, capable of disassemblage by theremoval of said pivot rod. To such ends said pivot rod is provided withan operating. handle 9 Y of any usual form for convenient manipulation.I

In the preferred construction shown, the pivot rod 8 is formed with anon-circular portion 10 adapted to engage in a similarly formed outerknuckle 7 of a deflector plate 4 to provide an operative connectionwhereby'a swinging movement of said deflector plate 4 can be attained bya corresponding turning movement of said pivot rod by the operator. 7 I

In actual use, and with the ash pan 3 in place in the ash pit, thedeflector plates 4 are turned into an inclined position with their freeends resting against the side walls of the ash pit as shown. When it isdesired to remove the ash pan, the deflector plates 4' are turned overonto the top of the ashes in said pan, to cover and inclose the same,after which the ash pan is withdrawn from the ash pit for the ordinarydumping operation. When through neglect on the part of the attendant theashpit becomes unduly filled and clogged up with ashes, thus preventinga local operation of the deflector plates and a removal of the ash panwith said plates connected thereto, the present improvement affords aready means for over- 7 coming the difliculty, by a removal of the pivotrods 8, so as to permit of a separate withdrawal of the ash pan proper,a subsequent withdrawal of the deflector plates and nary manner.

11 designates bent wings formed-011 the free forward corners of thedeflector plates 4, adapted on a closure of said plates to embedthemselves in the top portion of the ashes to more effectually retainsaid deflector plates in place over the body of, ashes.

Having thus fully described my said in- -9zs a removalof the surplusashes in the ordi- V 1 vention, What I claim as new and desire to sbetween said pan and plates, said rods being secure by Letters Patent,is: removable When the ash pan is Within the The combination with an ashpan of the ash pit to permit a separation of the plates 10 typedescribed, of a pair of deflector plates from the pan substantially asset forth. 5 pivotally associated with the side Walls of Signed atChicago, Illinois, this 30th day the ash pan, and longitudinallyremovable ofNovember, 1917. pivot rods constituting the pivotconnections v JOHN J. PROCHAZKA.
